International Comfort Products GPCM42K100F Thermistor
A thermistor is a special kind of new age resistor whose resistance changes as it depends on current temperature. The system control board must know the temp in certain areas to understand what is going on. They can tell the HVAC system when a temperature reaches a certain point.
What are the indications that my temp regulating thermister is not working properly?
- The main fan refuses in the attempt to ramp up to full speed
- The initial sequence could never start up depending on which is the thermistor that is damaged
